Inhibitory potential of proanthocyanidins from the fruit pulp of Clausena lansium (Lour.) Skeels against α-glucosidase and non-enzymatic glycation: Activity and mechanism

Inhibiting the activity of α-glucosidase and glycosylation of protein is an important way to treat diabetes mellitus and its complications. In this study, we investigated the anti-α-glucosidase activity, anti-glycation potential and structure of proanthocyanidins from fruit pulp of Clausena lansium (Lour.) Skeels. C. lansium fruit pulp proanthocyanidins showed a remarkable inhibition against α-glucosidase activity with IC50 vaule of 0.26 ± 0.01...
